No - please check the attached pictures and try to imagine to draw the white rectangle just with your PC mouse.#1 = first click, #2 = second click, #3 = third click with the left mouse button. And you can use the snap function for all those clicks ....

OK - now we are no longer talking about a simple 3 point rectangle tool.Yes I would also like to have an extra field for angle input but then - we have to go the whole hog!

NOW I like to have 3 tools ...

1. A new rectangle tool, 3 points, free angle (as described),2. Modifying the existing 2 point "Rectangle tool"(RE) with an option box "restricted" to x, y or not (= free rotation),3. Modifying the existing "Rectangle with size tool"(RS) with an additional option to use a given angle value or to keep the orientation restricted to x,y
